But wait! Just because Nathan Fillion isn't playing Nova in Guardians of the Galaxy doesn't mean he's not in the movie. Proving that he's no liar, James Gunn goes onto confirm that his friend is in fact in the movie. He's just not playing Nova.

"@STARS_TyranT: Are the rumours true that he has some part in the film?" @nathanfillion has a very small fun cameo he did as a favor to me.

This begs the question, 'Who is he playing?' And, 'Do you care?' Will Nova still appear in the post-credits sequence? That was not denied. And as we pointed out yesterday, Nova wears a helmet, so any actor could play him in a post-credit sequence and be replaced, ala Marvel's The Avengers and Thanos.
